메시지: 개체 참조가 개체의 인스턴스로 설정되지 않았습니다.

타겟 세그먼트를 클릭할 때마다 "개체 참조가 개체의 인스턴스로 설정되지 않았습니다." 라는 메시지와 "Key"라는 메시지가 뜹니다.

두 메시지 모두 오류 파일을 저장해 두었습니다. 어떻게 고칠 수 있을까요?

  • First of all I'd recommend you upgrade your version of Studio to the latest one.  You should be seeing the notification in the orange bell at the top right of your Studio application.

    If that doesn't help then I think the next thing to try is a simple reset. This often cures all ills where there are no other explanations.  

    Rename this folder (just add _old to the end or something, it's not important what you rename it to) and restart Studio:

    c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\15.0.0.0

    So the path would become this:

    c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\15.0.0.0_old

    If you can't find this folder then you need to unhide your hidden files/folders:
